摘要：

This paper studies mixed finite element approximations to the solution of the viscoelasticity wave equation. Two new transformations are introduced and a corresponding system of first-order differential-integral equations is derived. The semi-discrete and full-discrete mixed finite element methods are then proposed for the problem based on the Raviart-Thomas-Nedelec spaces. The optimal error estimates in L-2-norm are obtained for the semi-discrete and full-discrete mixed approximations of the general viscoelasticity wave equation.
